DETAILED DESCRIPTION OF EMBODIMENTS

Attention is first directed to FIG. 1 of the drawings illustrating a utility system generally designated 10 and comprising a dolly cart 12 with a stack of three utility units 14 articulately mounted over the dolly cart 12. The utility units 14 are three containers, e.g. tool or storage containers 16A, 16B and 16C, each articulated to a container below, respectively, and wherein the lowermost container 16A is in turn articulated over a top surface of the dolly cart 12, as will be discussed hereinbelow. It is appreciated that the utility units 14 can be article of utility as defined herein before, and each have a different size and footprint, however configured for respective articulation over one another, and over the dolly cart 12.

Whilst the description and drawings herein refer to utility units being containers, it should be appreciated that the scope of the disclosure is not to be restricted to same.

FIGS. 2A to 2C are directed to the dolly cart 12, and it can be seen that the dolly cart comprises a mounting platform 20 configured with four caster wheels 22 articulated at a bottom surface of the dolly cart, with a top bearing face 26 configured with several utility unit positioning depressions 28 and 29. These are positioned and shaped in register with corresponding projections at a bottom surface of a second utility unit to be mounted thereover, e.g. container 16A as discussed in connection with FIG. 1 .

The dolly cart 12 is further configured with a pair of pivoting latch members 30, each pivotally disposed within a niche 32 of a respective side wall 34 of the dolly cart 12, and configured for articulating with locking retaining members of a second utility unit (e.g. container 16A, and as will be discussed with greater detail with reference to FIGS. 6A and 6B). The pivoting latch members 30 are configured with a gripping portion 38 suited for comfort grabbing by an individual when carrying same, whereby the latch members constitute also carrying handles. The pivoting latch members 30 are pivotable between a collapsed position (left side latch member of FIGS. 2B and 2C), and a locking position (right side latch member of FIGS. 2B and 2C)

It is now appreciated that the second utility units, e.g. containers 16A to 16C illustrated in FIG. 1 and as will be discussed with reference to several figures hereinafter, are each configured with pivoting latch members 30 at respective side ends thereof or over a top bearing surface thereof, however disposed within a niche.

As can be further seen, the pivoting latch members 30 are pivotally secured within the niche 32 by a pair of connectors 40, snappingly secured within the niche 32 and each configured with an indention 42 for at least partially receiving the pivoting latch members 30, whereby at the collapsed position the latch members 30 substantially do not project from the top bearing face 26 nor from the side walls 34. From the arrangement of FIG. 3 it can be realized that the connectors 40 with the pivoting latch members 30 can be configured as kit, rendering it suitable for attachment to other utility units, so as to readily convert them into a component utility unit of the utility connectivity system according to the present disclosure.

Turning now to FIG. 4 of the drawings, there is illustrated a trolley-style first utility unit in the form of a rigid trolley-style wheeled container 46, comprising a rigid body 48 with a pair of locomotion wheels 50 at a base portion of the container, a telescopic handle 52 retractable from the body 48, and a pivotally secured top cover 54. The cover 54 comprises a bearing surface with shaped depressions 55 configured for receiving and supporting projections disposed at a bottom face of a second utility unit (not shown) to be mounted thereon, and further comprising a pair of pivoting latch members 56 spaced apart near side end portions of the cover 54 and disposed within a depressed niche 58, such that at a collapsed position, the latch members 56 substantially do not project from the top surface of the cover 54. The depressed niches 58 are configured with an opening facing the respective nearby side wall, whereby the pivoting latch members 56 are easily accessible also at the presence of a second utility unit over the first utility unit.

FIGS. 5A, 5B and 5C exemplify modularity of the connectivity system, wherein in FIG. 5A the system 60 comprises a first utility unit 62 (same as trolley-style wheeled container 46 of FIG. 4 ), and the second utility unit articulated thereover is a container (same as container 16B in FIG. 1 ), however with the footprint of the second utility unit being smaller than that of the first utility unit 62, and wherein the longitudinal axis of the two containers are disposed parallel to one another and perpendicular to an axis of the wheels 50. In FIG. 5B the first utility unit 68 (same as first utility unit 62 in FIG. 5A) and the second utility unit articulated thereover is an organizer box 70, and likewise is the third utility unit 72. Similar to the arrangement in FIG. 5A, the footprint of the second utility unit 70 (and 72) is smaller than that of the first utility unit 68. The arrangement of FIG. 5C discloses a first utility unit 78 (same as first utility unit 68 in FIG. 5B) and two second utility units 80 and 82 (schematically represented) and articulated over the first utility unit 78 at a side-by-side orientation, with the axis of the two second utility units 80 and 82 traversing the longitudinal axis of the first utility unit 68 (i.e. parallel to the axis of the wheels 50). However, the coupling arrangement of the utility units disclosed hereinabove in connection with FIGS. 5A to 5C is similar to the disclosure relating to previous examples and with particular reference being made now to FIGS. 6A and 6B.

As seen in FIG. 5A, and better in FIGS. 6A and 6B (being a close-up of detail A is FIG. 5A), each second utility unit (e.g. container 64) is configured at a bottom portion of its opposite side walls 90 with a retaining member 94 in the form of a pair of rigid upwards facing hook-like element integrally formed on and outwardly protruding from the respective side wall. The retaining member 94 can be in the form of a couple or more such hook-like elements (e.g. as in the illustrated example) or it can be a continuous element (not shown). The pivoting latch members 56 are pivotally articulated to the cover 54 at the niche 58, through a bushing support 98 comprising a spring biased plunger mechanism 100 configured for retaining the latch member 56 at a closed position, when not in use. Also noted, the niche 58 comprises an arresting rib 59 whereby when the latch members 56 is disposed at the unlocked position it is unlikely to spontaneously displace (i.e. it remains disposed substantially parallel over the base surface 61 of the niche 58 and not projecting therefrom)

In use, the latch members 56 are retained at the unlocked position (i.e. resting within the niche 58) and the second utility unit, namely container 64 of the present example, is placed over the first utility unit, namely trolley 46. Once positioned in place, the latch members 56 are pivoted upwards towards one another so as to engage and arrest with the retaining members 94, whereupon the second utility unit is articulated over the first utility unit and they can now be locomoted unitarily. Likewise, a third utility unit can now be articulated over the second utility unit (e.g. as in the example of FIG. 1 or 5B). Detaching the second utility unit from the first utility unit is easily facilitated by pivotal displacing the latch members 56 into their resting, unlocked position (FIG. 4 ). It is noted that upon displacing the latch members 56 into the locked position they snap into arresting by the respective retaining members 94, whilst unlocking requires applying some force so as to overcome the arresting bulge at the tip of the retaining members 94.

Further attention is now directed to FIGS. 7A to 9B of the drawings, illustrating another example of a utility connectivity system according to the disclosure.

A trolley-style first utility unit in the form of a rigid trolley-style wheeled container 100, comprising a rigid body 102 with a pair of locomotion wheels 104 disposed at a base portion of the container and rotatable about an axis 105, a telescopic handle 106 retractable from the body 102, and a pivotally secured top cover 110. The cover 110 has a bearing surface 111 comprising a pair of pivoting latch members 114 spaced apart and disposed within a depressed niche 116, such that a major portion of the latch members 56 extends within the niche 116 (at either a locked/unlocked position thereof), however with only locking tongue projecting over the bearing surface 111, as will be discussed. Each pivoting latch members 114 comprises a pair of tongue-like locking latches 115 (seen in FIGS. 7C-7D). The pivoting latch members 114 are pivotally articulated to the cover 110 through axel disposed parallel to the wheels axis 105.

As seen in FIG. 7A, the right side niche 116 is configured also with an opening facing the respective nearby side wall, however wherein both pivoting latch members are easily accessible also at the presence of a second utility unit (120; FIG. 7B) over the first utility unit 100.

As seen in FIGS. 7B, 9A and 9B, the second utility unit, namely container 120, is configured at a base thereof with a bearing portion 130 having a bottom surface 132 and a rim 134 (peripheral in the present example), said bearing portion 130 shaped and sized for at least partial nesting within boundaries of a top nesting portion defined by a support rim 136 of a like container, at a stacked position (not shown), such that a bottom surface 132 of top container bears over a top surface 135 of a bottom container. The second utility unit 120 is configured at least at respective opposite sides of the bearing portion 130 with two locking receptacle 138 having a lateral opening.

Reverting to the pivoting latch members 114, the tongue-like locking latches 115 are displaceable through latch passages 140, wherein the locking latches 115 are displaceable between the locked position at which they project inwardly and over the support surface 111, and the unlocked position wherein the locking latches 115 are retracted, i.e. do not project over the support surface 111, at which position the latches are protected and are not exposed to undesired impact.

The arrangement is such that articulating the second utility unit 120 over the first utility unit 100 is facilitated by placing the former over the later such that the bottom surface 132 bears over the support surface 111, wherein the locking receptacles 138 are in register with the locking latches 115, whereby pivoting the latch members 114 into the locked position (FIGS. 7C, 7E, 7F and 8B), the locking latches 115 engage within the respective locking receptacle 138 of the second utility unit 120, such that the two utility units are articulately connected to one another.

At an unlocked position (FIGS. 8A to 8B) the locking members 114 are pivotally displaced outwards, wherein the locking latch 115 disengage from the respective locking receptacle 138, wherein the second container can be separated from the first container. It is noted that pivotal displacement of the pivoting latch members 114 is restricted within latch passages 140, whereby upon pivotal displacement of the latch members 114 into the fully open position a stopper portion 117 of the locking latches 115 encounters a wall surface 144 of a bridge portion.

The disclosed arrangement facilitates articulating a second utility unit over a first utility unit, the former having a smaller footprint than the latter.

With reference made to FIGS. 10 to 13 , there is illustrated a first utility unit in form of a mounting platform 160, configured for articulation thereto a second utility unit in form of a container 164 (e.g. a tool box or the like).

The mounting platform 160 is made of rigid material and comprises a bottom face 166 suitable for mounting over any bearing surface such as a truck bed, a work station and the like, and securing thereto with bolts through a plurality of openings 118. A top face 170 (seen in FIGS. 11A and 12 ) of the mounting platform 160 mimics a top face of utility unit as disclosed hereinabove, e.g. dolly cart 12 of FIGS. 2A-2C, or a top face of a container as mentioned hereinbefore. The top face 170 is configured for bearing bottom surface portions of a second utility unit, and is further configured with several positioning locations, e.g. depressions 171 for receiving and positioning respective projections 173 of the second utility unit 164.

The mounting platform 160 is further configured with a pair of pivoting latch members 172, each pivotally articulated, within a niche 174 at opposite sides of the platform 160, pivoting latch members 172 configured for articulating with laterally extending locking retaining members 178 of the second utility unit 164. The pivoting latch members 172 are configured with a gripping portion 180 suited for comfort grabbing by an individual when carrying same, whereby the latch members constitute also carrying handles. The pivoting latch members 172 are pivotable between an unlocked/collapsed position (right side latch member in these Figures), and a locking position (left side latch member of the respective Figures).

When a second utility unit 164 is placed and positioned in register over the mounting platform 160, the latch members 172 can be pivoted into their locked position for arresting the locking retaining members 178 of the second utility unit.

FIGS. 14A to 16 illustrate a second utility unit being a workbench platform 190 mountable over a first utility unit, which in the present example is a container 192 (though it could just as well be any other utility unit (e.g. mounting platform 160 of the previous example, or other types of containers, etc.). The workbench platform 190 comprises a flat top surface 194 and a flat bottom surface 195 (though these could be configured with various working/machining configurations common with working surfaces). An intercoupling unit 196 is configured at a bottom face, constituting an intercoupling unit for articulating the platform to a first utility unit as will be explained. The intercoupling unit 196 can be integral with the workbench or attached thereto, whereby at the event of wear of one surface, the work surface can be turned over and attached over the intercoupling unit 196 for using the opposite surface. It is also seen that the intercoupling unit 196 has a smaller footprint than the work surface, though other proportions are possible as well.

The intercoupling unit 196 disposed below the work surface is configured at opposite sides thereof with laterally extending locking retaining members 200, similar to hook-like members 94 (FIGS. 6A-6B) or locking retaining members 178 (FIGS. 10, 13, 14A and 14B). Once the workbench platform 190 is placed over the first utility unit, e.g. container 192, or mounting platform 160 (FIG. 11A), the pivoting latch members 172 can be pivotally displaced into their respective locked position (FIG. 14B) for articulating the workbench platform 190 over the first utility unit.

In FIGS. 15 and 16 the workbench platform 190 constitutes a second utility unit articulated over a container 192 constituting a first utility unit with respect thereto, whilst the container 192 is in turn is articulated over a mounting platform 160 which constitutes a first utility unit with respect to the container 192 (which is then the second utility unit, respectively).
